On the most recent patch (currently update #2 I believe) when you interact with the synthesis machine (or whatever it's called. It's the machine you interact with after the milking machine back on the ship) it still says that you need to milk yourself first even if you have. It then proceeds to activate a small cutscene and then you can interact with the machines below it to grab the item anyway. (Not sure if dialogue is missing or if it just says that line first either way)
